Dedifferentiation occurs during the formation of

Options

A. Cork cambium
B. Vascular cambium
C. 1 & 2
D. Sclerenchyma

Answer

**Step-by-Step Text Solution:**

1. **Understanding Dedifferentiation**: Dedifferentiation refers to the process where specialized, differentiated cells revert to a more primitive, unspecialized state. This often involves a permanent tissue transforming back into a meristematic tissue, which can divide and contribute to growth.

2. **Identifying the Context**: In plants, dedifferentiation is crucial during specific growth processes, particularly during secondary growth. Secondary growth involves the increase in thickness or girth of the plant, which is facilitated by certain types of meristematic tissues.

3. **Recognizing the Types of Tissues**: The two types of cambial tissues involved in secondary growth are:
- **Vascular Cambium**: This tissue is responsible for the formation of secondary xylem (wood) and secondary phloem (inner bark).
- **Cork Cambium**: This tissue produces cork cells, which form the outer protective layer of the plant.

4. **Linking Dedifferentiation to Cambial Formation**: During secondary growth, both vascular cambium and cork cambium arise from dedifferentiation of permanent tissues. This means that specialized cells in the plant revert to a meristematic state to allow for further growth and development.

5. **Conclusion**: Therefore, dedifferentiation occurs during the formation of both vascular cambium and cork cambium, as these processes involve the transformation of permanent tissues back into meristematic tissues.

**Final Answer**: Dedifferentiation occurs during the formation of vascular cambium and cork cambium.
